Hearing Xiu's words, Asuma choked on a puff of smoke out of nowhere and started coughing frantically.
As he coughed, he looked over at Xiu.
He saw that Xiu's originally pitch-black eyes had turned a flawless, pure white, with extremely faint meridian veins spreading out from the corners of his eyes.
Seeing this, Asuma's voice changed pitch slightly: "Byakugan? How do you have the Byakugan?!"
"Is there a problem with the Byakugan? Doesn't the Uchiha----" Might Guy looked back at Xiu belatedly, then reacted violently: "The Byakugan?!! How do you have the Byakugan?!"
"Your reaction is too slow, Guy----"
Kakashi shook his head with a chuckle. To be honest, he wouldn't find anything strange no matter what happened to Xiu.
After all----he had even seen Rin after she was resurrected.
Dead people could be resurrected, so awakening a Byakugan was nothing strange at all.
"Although it's unbelievable, according to historical records, the Uchiha's Sharingan originally originated from the Byakugan. Xiu's situation should be considered an atavism, right?"
As he spoke, Kakashi cast an inquiring gaze at Xiu.
Xiu looked out toward the examination hall and said casually, "The Uchiha and the Hyuga do share the same ancestral bloodline, but what you said isn't entirely correct. The Byakugan and the Sharingan are two different systems of power."
The evolution sequence of his dojutsu was Mangekyo -> Rinnegan -> Byakugan.
When the amount of chakra in his body reached a certain level back then, he naturally awakened Wood Release. Although he didn't have the chakra of Asura and Indra, his body also automatically evolved the Power of All Creation, unlocking the Rinnegan.
However, as nice as the Rinnegan's abilities were, it couldn't be switched back to a normal state.
Xiu simply couldn't accept those purple onion rings, so he hardened his heart
